4G not working

I have just recently joined Vodafone last week but my experience so far is just horrible. I got new iphone 7 on contract, last Tuesday my sim got active after 50 hrs of purchase and since then I cant get 4G on my device.

I have contacted many advisors online on vodafone and have also gone to store twice. They swapped my sim reset setting but no luck.

Now Yesterday an online agent told that my number is not configured on something called TRACS. But since then 24+ hrs still no 4G.

If anyone can help me here that would be great. Else I would have no option other than leaving vodafone.

Also went to the store twice. Once they swapped the sim it didnt work and then in next visit they told me that everything on my account is fine this issue will be solved by the tech team which can only be contacted online or on phone. At store level we can do nothing more for you.

Thank for your response. Actual reason is that im in cooling off period and want to test 4G coverage of vodafone before i make decision to stay with them for 2 years. 3G coverage is good but i have to test 4G coverage too.
